In mathematics, a ruled variety is a variety birational to a product of the projective line and another variety, and a uniruled variety is a variety that is dominated by a ruled variety. This concept is a generalisation not too remote of the ruled surface s of classical differential geometry. A variety is uniruled if and only if there is a rational curve passing though every point. Any uniruled variety has Kodaira dimension &minus &infin . In dimension at most 3, and conjecturally in all dimensions, the converse it true a variety of Kodaira dimension &minus &infin is uniruled.

Unreferenced date January 2010 About the taxonomic rank in botany Variety disambiguation In botanical nomenclature , variety abbreviated var. in Latin varietas is a taxonomic rank below that of species as such, it gets a ternary name a name in three parts . A variety will have an appearance distinct from other varieties, but will hybridize freely with those other varieties if brought into contact . Usually varieties will be geographically separate from each other. Example The pincushion cactus, Escobaria vivipara Nutt. Buxb., is a wide ranging variable species occurring from Canada to Mexico , and found throughout New Mexico below about 2600 m. Nine varieties have been described. Where the varieties of the pincushion cactus meet, they intergrade . The variety Escobaria vivipara var. arizonica is from Arizona , while Escobaria vivipara var. neo mexicana is from New Mexico. Notes To plant breeders, at least in countries that are signatory to the UPOV Convention, variety plant variety or plant variety is a legal term. In zoological nomenclature , the only allowed rank below that of species is that of subspecies . A name that was published before 1961 as that of a variety is taken to be the name of a subspecies. A name published after 1960 as that of a variety does not formally exist. In zoology, Form zoology forms and Morph zoology morphs are used informally if needed, but are unregulated by the International Code of Zoological Nomenclature ICZN . In bacteriological nomenclature variety is not allowed, but names published as varieties before 1992 are taken to be published as subspecies. In viticulture , what is referred to as grape variety grape varieties are in reality cultivar s according to usage in the International Code of Nomenclature for Cultivated Plants or variety ..., usage of the term variety is so entrenched in viticulture that a change to cultivar is unlikely.

In mathematics , the Albanese variety A V , named for Giacomo Albanese , is a generalization of the Jacobian variety of a curve, and is the abelian variety generated by a variety V . In other words there is a morphism from the variety V to its Albanese variety A V , such that any morphism from V to an abelian variety factors uniquely through A V . For complex manifolds harvtxt Blanchard 1956 defined the Albanese variety in a similar way, as a morphism from V to a torus A V such that any morphism to a torus factors uniquely through this map. Although it is called a variety in this case, it need not be algebraic. For compact space compact K hler manifold s the dimension of the Albanese is the Hodge number h sup 1,0 sup , the dimension of the space of differentials of the first kind on V , which for surfaces is called the irregularity of a surface . In terms of differential form s, any holomorphic 1 form on V is a pullback differential geometry pullback of an invariant 1 form on the Albanese, coming from the holomorphic cotangent space of Alb V at its identity element. Just as for the curve case, by choice of a base point on V from which to integrate , an Albanese morphism math V to operatorname Alb V math is defined, along which the 1 forms pull back. This morphism is unique up to a translation on the Albanese. For varieties over fields of positive characteristic, the dimension of the Albanese variety may be less than the Hodge numbers h sup 1,0 sup and h sup 0,1 sup which need not be equal .

In mathematics , a quasiprojective variety in algebraic geometry is a locally closed subset of a projective variety , i.e., the intersection inside some projective space of a Zariski open and a Zariski closed subset. A similar definition is used in scheme theory , where a quasiprojective scheme is a locally closed subscheme of some projective space. ref http eom.springer.de q q076660.htm ref Relationship to affine varieties For example, affine space is a Zariski open subset of projective space , and since any closed affine subset math U math can be expressed as an intersection of the projective completion math bar U math and the affine space embedded in the projective space, this implies that any affine variety is quasiprojective. There are locally closed subsets of projective space that are not affine, so that quasiprojective is more general than affine. Taking the complement of a single point in projective space of dimension at least 2 gives a non affine quasiprojective variety. This is also an example of a quasiprojective variety that is neither affine nor projective. Examples Since quasiprojective varieties generalize both affine and projective varieties, they are sometimes referred to simply as varieties . Varieties isomorphic to affine algebraic varieties as quasiprojective varieties are called affine variety affine varieties similarly for projective varieties. For example, the complement of a point in the affine line, i.e. math X mathbb A 1 0 math , is isomorphic to the zero set of the polynomial math xy 1 math in the affine plane. As an affine set X is not closed since any polynomial zero on the complement must be zero on the affine line.

In mathematics , a norm variety is a particular type of algebraic variety V over a field mathematics field F , introduced for the purposes of algebraic K theory by Voevodsky . The idea is to relate Milnor K theory of F to geometric objects V , having function field s F V that split given symbols elements of Milnor K groups . The formulation is that p is a given prime number, different from the characteristic algebra characteristic of F , and a symbol is the class mod p of an element math a 1, dots, a n math of the n th Milnor K group. A field extension is said to split the symbol, if its image in the K group for that field is 0. The conditions on a norm variety V are that V is irreducible and a non singular complete variety . Further it should have dimension of an algebraic variety dimension d equal to math p n 1 1. math The key condition is in terms of the d th Newton polynomial s sub d sub , evaluated on the algebraic total Chern class of the tangent bundle of V .

In mathematics , the Jacobian variety J of a non singular algebraic curve C of genus mathematics genus g is the group of divisor algebraic geometry divisors on C of degree 0, modulo Adequate equivalence relation rational equivalence . The Jacobian variety is a principally polarized abelian variety , of dimension g , and hence, over the complex numbers, it is a complex torus . If p is a point of C , then the curve C can be mapped to a subvariety of J with the given point p mapping to the identity of J , and C generates J as a Group mathematics group . Over the complex numbers, it can be realized as the quotient space V L , where V is the dual of the vector space of all holomorphic differentials on C and L is the lattice of all elements of V of the form math omega mapsto int gamma omega math where is a closed path topology path in C . The Jacobian of a curve over an arbitrary field was constructed by harvtxt Weil 1948 as part of his proof of the Riemann hypothesis for curves over a finite field. The Abel Jacobi theorem states that the Jacobian of a curve can be identified with its Picard variety of degree 0 divisors modulo linear equivalence. For varieties of higher dimension the construction of the Jacobian variety as a quotient of the space of holomorphic 1 forms generalizes to give the Albanese variety , but in general this need not be isomorphic to the Picard variety. Torelli s theorem states that a complex curve is determined by its Jacobian with its polarization . The Schottky problem asks which principally polarized abelian varieties are the Jacobians of curves. The Picard variety , the Albanese variety , and intermediate Jacobian s are generalizations of the Jacobian for higher dimensional varieties. References cite book author P.
